T0 all mhbm it may concern: I

Be it known that 1, CHARLES A. IPSILAN- DER, a citizen of the United States, and a resident of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Im rovement iuSus ension Means for Electricailway Motors, 0 which the following is a s e'cification. My invention re ates to suspension means forjelectricrailway motors of theclass in which the armature of the motor is mounted upon or surrounds the driving-axle.

I The object of my inventionis to provide.

such means-for supporting a lar e art of, the weight of the motor on the true ame that the motor shall be substantially independent of all; distortions and tilting movements of such frame and the motor-bearings shall be relieved of the weight of the fieldmagnet frame.-

invention is illustrated in theaccompanying drawings, in which I F gure 1 is a view, partially in side eleva tion and partially in section, of a locomotivetruckembodying my invention. 2 is a view in end elevation of the truck shown in Fig. 1, some of the parts being broken away for the sake of clearness of illustration. Figs.

- 3 and 4 are enlarged sectional views of resilient tures 4 are mounted. Field-magnet frames.

5 ofthe motors are provided with bearings 6 for the quills 3, thus permittin of rotation of the armatures 4 and quills 3 in ependently of the ield-magnet frames. I The provided at each end with radial arms 7, which carry at their outer ends removable wearing pieces 8. The inner sides of the driving-wheels 2 are'provided with annular recesses 9, in which casings 10 are secured. Ifhese casings 10 contain sprin s 11 and caps 12, and the projecting ends 0 the caps engage the we aring-pieces 8 of the arms 7. The springs 1 1 are compressedbefore being placed in the casings 10, and the motor issupported under all conditions .by the arrangement here shown with its axis approximately coincident with the axis of the driving-axle.

The outer ends of the driving-axle 1 are suspen'sionand connection means between a- I scription,

uills 3 are provided with journal-boxes 15, which are seated in and support a truck-frame 16. Leafsprings 17 are securedmidway of their ends to the tops of the journalboxes 1'5, and their ends are connected, by means of links 18 and 19, respectively, to the truck-frame and to equalizing-levers 20, springs 21 being interposed between theequalizlngdevers and the main truck-frame. I

The truck-frame 16- is provided with -oppositely-projecting bracket-arms 22, and the end pieces 23 of the truck-frame are rovided with inwardly-projecting lugs 24.

om the bracket-arms 22 and lugs 24 leaf-sprin s 25 are supported by means of suspensions I 26, centrally-located lugs 14 upon the motorfield-magnet frames being secured to the mid- .1

dle points of the leaf-springs.

v Rotation of the motor-field-magnet frames by reason of the torque exerted between the field-magnet Eoles and the armatures is pre vented'by'l 27, which are connected between lugs28 upon the up er and lower sides of the motors and the true -frame 16.

It is evident that my invention provides suspension means for railway-motors whereby the tilting" movements and distortionsof the truck-frame are transmitted in a mimmum degree to the motors. the truck-frameshould be suddenly raised.

If one side of while the other side remained in its original position, only one half of the distortion would be transmitted to the motor without theintervention of s rings, and by the use of these sprin s,- as out ined in the foregoing det e distortion is reduced to a minimum. I I

I I claim as my invention tion with a truck-frame, a driving axle, a

ings for said armature, of lugsintegral with said frame and leaf-s rings having their mid- I 1. In an electric locomotive, th'e combinadle portions attache to said lugs and having 7 1 their ends secured to said truck-frame".

2. In an electric locomotive, the combiriation with a truck-frame, a driving-axle,a mo- IOO tor-armature flexibly mountedthereon, and

a field-magnet frame surroundin and havin bearings forsaid armature, of ugs integra I with said field-magnet frame, and leaf-springs having their ends secured to said truck-frame and their middle portions secured to said lugs.

3. In an electric locomotive, the combination with a truck-frame, a driving-axle, a motor-armature flexibly mounted thereon, and

a field-magnet frame surroundin and having bearings for said armature, of ugs integral with said field-magnet frame, leaf-springs havin their ends securedto said truck-frame and t eir middle portions secured to said lugs, and links between said motor and said truck-frame.

g 4. In an electric locomotive, the combination with a truck-frame, a driving-axle, a motor-armature flexibly mounted thereon, and afield-Ina et frame surroundin and having bearings or said armature, of ugs integral with said motor-frame, leaf-springs having their ends secured to said truck-frame and their middle portions secured to said lugs, and links attached respectively to the upper and lower sides of the motor-frame and to the truck-frame.

5. In an electric locomotive, the combination'with a truckframe, a driving-axle, a motor-armature flexibly mounted thereon, and a field-magnet frame surrounding and having bearings for said armature, of a centrally-located lug on each side of the motor-frame, and leaf-springs havin their ends supported by the truck-frame and their middle portions secured to said lugs.

6. In an electric locomotive, the combination with a truck-frame, a driving-axle, a ouill surrounding said axle and connected t ereto, a motor-armature mounted on said quill, and a motor-field-magnet frame having bearings for said quill, of a centrallylocated lug on each side of the motor-frame, and springs having their ends supported by the erases trueleframe and their middle portions secured to said lugs.

7. In an electric locomotive, the combination with a truck-frame, a driving-axle, a motor-armature flexibly mounted thereon, and a motor-field-magnet frame having bearings for said armature, of a pair of links suspended from the truckframe' at each side of the motor and a spring interposed between each side of the motor-frame and the correspondinglinks.

8. In an electric locomotive, the combination with atruck-frame, a driving-axle, a motor-armature flexibly mounted thereon, and a field-magnet frame having bearings for said armature, of sprin connections between the middle portions oi the field-magnet frames and the truck-frame adjacent to the ends oi the motor.

9. In an electric locomotive, the combination with a truck-frame and its axles, of an electric motor having its armature loosely sleeved upon one of said axles and spring connections between substantially the middle point of each side 0? the field-magnet frame of the motor and the truck-frame.

10. In an electric locomotive, the combina tion with a truck-frame and its axles, of an electric motor having its armature loosely sleeved upon one of the axles and leaf-springs connected at their middle points to the middle points of the sides of the motor field-magnets and at their ends to the truck-franu-.

In testimony whereof I have hereunto subscribed my name this 30th day of March,

CHARLES A. PSILANDER.
